BINDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 665,483, dated January 8. 1901. 1 Application filed August 24, 1899' Serial No. 728,272. (No modeLl v To all whom it may concern: cable to the ordinary U-shaped binder in Be it known that I, AURELIUS STEWARD, a common use. citizen of the United States, and a resident of The bed-plate A of the sewing-machine and Bridgeport, in the county of Fairfield and its cloth-feeding and stitch-forming mechan- 5 State of Connecticut, have invented certain ism are allof usual construction.

As the plate F serves the 5 vertical shaft; but it isequally adaptable to purpose of carrying the hinder-head and the machines employing shuttles or other variety friction-pins and also of covering the openof thread interlocking mechanism. The ing in the bed-plate A, which is left for the binder-head employed is of that class in the insertion of the bobbin, I will term it the passing of which by turning a nearly abrupt bobbin-cover F. 50 angle the binding is changed from a convex While the front end of the bobbin-cover is to a concave form; but it is equallyappliof sufficient width to serve the purpose its name would indicate, yet its middle portion is so narrowed down, as seen in Figs. 1 and 2, and the bracket II is of such a width that both shall be somewhat flexible and yielding for purposes hereinafter explained. At the end opposite the binder-head it will be seen that the bobbin-cover has an angular extension. This and the consequent necessary elongation of the bracket H are in order that the pivot-screw f may be located on a line with the farther edge of the bobbin-cover. In-that location of the pivot it will be seen that the bobbin-cover draws promptly away from the throat-plate and presser-foot on being drawn aside, as seen in Fig. 2. The curvature of the bracket H is in order that its edge may not by contact with the friction-pins too much restrict the withdrawal of the cover. When in operative position, the downward pressure of the bobbin-cover F and bracket [-1 is sufficient to retain the cover between the ribs upon the bed-plate A and press the binderhead B down upon the bottom of the recess d in the throat-plate D. As thus located the binder-head is so deeply seated in the deepened recess before referred to in the throatplate D that the center of its open mouth through which the cloth passes is but slightly above the upper surface of the throat-plate. In this condition if a thin fabric be passed through the binder it enters on a plane even with the upper surface of the throat-plate on which it lies and passes through the center of the aperture in the binder, as may be seen in Fig. 5. If, on the contrary, a thick fabric he passed through or thick places in the fabric occur even to the full capacity of the hinder, the binder-head is by its flexible and yielding connection permitted to rise and still present the center of its aperture to the material, as shown in Fig. 6. This is especially beneficial in binding corsets, where the material varies from a single ply to several thicknesses interlaid at frequent intervals with cords, bones, and reeds.

The recess between the ribs upon the bedplate A is of sufiicient depth to prevent displacement of the bobbin-cover F, while permitting the binder-head to rise and fall sufficiently to conform to the different thicknesses of fabric. WVhen the bobbin -thread is to be replenished, however, the operator may by means of the knob 70 lift the bobbin-cover out of the recess and swing it toward him to render the bobbin (shown at L) freely accessible, as shown in Fig. 2. By so doing the binding is not in the least disarranged, as a short stretch of binding is merely drawn through the binder-head from the source of supply, while that between the binder and the fabric is safely held against displacement. When the replenished bobbin has been inserted, it is only necessary to draw upon the slack binding hack of the friction-pins to cause all parts to resume their correct posiiion, when the stitching may be continued without any imperfection to indicate that the work has been interrupted.

Having thus described my invention,'what I claim as new, and desire to secure by Letters Patent, is

1. In a sewing-machine the combination of stitch-forming mechanism with the resilient pivoted plate adapted to fit within the usual ribs on the sewing-machine bed-plate and carrying the binder-head, the throat-plate provided with a recess within which the nose of said binder-head normally projects, whereby the latter will be depressed within said recess when thin material is being operated upon and allowed to rise for the passage of thick material, substantially as set forth.

2. In a sewing-machine, the combination of stitch-forming mechanism,and a binder-head, with the resilient plate to which said binderhead is secured adapted to fit and be held within the usual ribs on the sewing-machine bed-plate, as described, and a bracket detachably secured to said bed-plate and having said resilient plate pivoted thereto, all substantiallyas and for the purposes specified.

Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 21st day of August, A. D. 1899.
